Susan,
I'm sorry I can not remember the name of the young man about 24 years old who was our guide. He spoke perfect English too. The guide and transportation was arranged through:

Maybe they can look it up and find out who was our guide, we flew to Igauzu Falls on Feb. 8, 2006 (Thomas & Marcie Matassa). Our order # printed on our confirmation is 0856.

I would recommend you reserve your room at the Sheraton ASAP. (we booked our own room). When I originally tried to get a room, Starwood (both on the phone and online) said they were sold out. I ultimately found our room at The Sheraton on an internet site called hotelclub.com which had a block of rooms reserved. They email you a voucher that you MUST present upon check-in. Because of having the Starwood AmEx card (or was because we have the AmEx Platinum card?) we were able to get the upgrade to our room facing the falls upon check-in subject to availability.

Good luck!
